Safe Boating Tips for the Florida Keys

Safe boating tips

Coral reefs and seagrass beds in the Florida Keys grow within inches of the water’s surface and can be found close to shore or several miles from shore. Learning to read water color in the Keys is important. It will help ensure a safe boating experience and it will help preserve our irreplaceable marine communities.

Reef formations that grow close to the water’s surface and shallow seagrass beds will make the water appear brown. Such areas should be avoided to keep from running aground and damaging both your boat and sensitive marine habitats.

White, white you’ll be there all night

Sand bars and shallow rubble areas appear white. These areas can be deceiving and may be much shallower than they appear. Navigate with caution around these areas.

Green, green nice and clean
Green water usually indicates an area free of shallow reefs or seagrass beds. Navigation of small, shallow draft boats in these areas is generally safe. However, larger, deeper draft boats should exercise caution. All boaters should carry and consult the appropriate NOAA marine chart.

Blue, blue cruise on through

Deep water areas, such as the ocean side of a reef may appear blue. Navigation in these areas is free from hazardous contact with reefs or seagrass beds. Remember, however, that coral reefs rise abruptly from deep water so give yourself plenty of room to maneuver.

If you run aground

Turn off your engine immediately. Do not attempt to use your engine to power off the reef or grass flat, which could damage your boat as well as these important habitats. If possible, raise your lower unit or outdrive and allow your vessel to drift free from the shallow areas. If you cannot drift free, radio for assistance on VHF channel 16.

Boat groundings can instantly pulverize coral, leaving areas open to infection by disease and devastate a thriving coral reel community that may take hundreds of years to rebuild.

Damage to seagrass beds can be equally devastating. Seagrass beds act as a nursery and feeding ground for numerous organisms. They also filter excess nutrients and trap sediments, thereby providing the clean, clear water essential for coral reefs. By running aground or even motoring in very shallow water, boats can scar seagrass beds. These narrow sand channels can grow wider and wider, decreasing the seagrass bed’s ability to protect the reef and provide a healthy community for marine creatures.

Helpful navigation hints

-Use extra caution when there is extensive cloud cover, a glassy calm sea state, extreme sun glare or murky water. These are condition when colors may not be apparent.

-Mooring buoys are located in the Florida Keys National Marine Sanctuary to keep boaters from damaging coral with their anchors. Some mooring buoys are located near extremely shallow reefs. Do not attempt to motor across a reef to reach a mooring buoy.
-Polarized sunglasses are very helpful in distinguishing water colors.

Do not approach these markers

-Reef light towers are prominent metal A-frame structures with a number posted on them.

-Shoal markers are solitary steel I-beams, standing approximately 10 feet, usually with a diamond-shaped DANGER sign attached.

-Many shallow reef areas are marked by reef light towers or shoal markers. If you look closely, you can determine where the shallow edge of these areas are located.

-Along the reef, there will often be a series of breaking waves.

-Along the edge of seagrass flats, you will frequently see a ripple effect or surface water texture change.

-Shallow sandbars will appear glassy.
